I agree with you that the decision to leave or stay is a double-edged sword, on the other hand this is an opportunity to change fate and career to a high level, but it all depends on Xabi decision between leaving this zone or staying. and the possible difficulty of finding other opportunities. In my opinion, Xabi should stay longer at Leverkusen to prove that there he really has a big influence on the team's performance, not just luck. Xabi does have the qualities of a great coach. 1 more season with Leverkusen is enough and he can accept the offer.
IMO, this is an opportunity for Xabi Alonso to spread his coaching wings. It was enough for Xabi to work with Leverkusen, so he could continue his coaching career with another club. in this way, its potential will be further honed and developed. especially, if Xabi leaves for the Premier League. this step will be a new start for him if he takes the opportunity for his future. ups and downs in building a team to become strong, is a process that will shape him into a qualified coach with experience. for me, there's nothing wrong if Xabi finally takes a new step next season. however, if Alonso still wants to hone his skills, the choice is in his hands by choosing Bayern Munich. with Bayern Munich, he moved up one step to handle a team at a different level than Leverkusen in terms of team depth. Bayern is still targeting the Bundesliga trophy, as well as testing its abilities in the Champions League. At the very least, this choice is the most ideal option rather than leaving to go to the Premier League which has several strong competitors. It's not certain that Xabi Alonso can directly lift Liverpool into an even stronger team. however, what is clear is that Xabi has been linked with two elite teams who want his services. Klopp sees that Xabi is his potential successor at Liverpool. Bayern wants Alonso to replace Thomas Tuchel. well, let's just wait and see how it develops. after all, the competition is getting closer to the end of the 2023-24 season. so, let's just wait for developments.
